Pro Circuit T4 or WB E-Series???

Question for the group....which exhaust should I get for my 650R? E-Series folks, how many discs are you running? Thanks for any input! Lee

I run the E series (with stock header) with 12 discs and the bike is uncorked. My friend runs a full T-4 system and has identical mods. Side by side there is very little difference in performance. I believe the E series has slightly more grunt in the low end while the T-4 seems to rev a little longer on the top end. If you are going to spend bucks on a full system then go with the T-4 if not, then go with the E-series - IMHO.
